Aquaductus networkus
Aquaductus networkus is an evolution of Lattachus multibranchus that accidentally evolved a splitting 3-way tube. It has become a multicellular organism with 2 different cells: a tube and a junction. They are able to transport important nutrients, compounds, gametes, and other materials throughout itself. It inhabits organic matter such as detritus and biofilm and release enzymes to mine and digest it. It can reproduce sexually or through fragmentation. Because it has dedicated so much space to its tube, it frequently forms a mutualistic relationship with Gigantocytus rhizoma.
